Cross-
Model
Truth.
Ask one question to dozens of AI models at once. ORBA groups their answers by meaning, so you see where they agree, where they split, and which one is the outlier.
One model is an opinion.
Many are a signal.
Every model has blind spots from its training. Asking models from different labs shows whether an answer is shared, or just one model's take.
Bias
Each lab trains on different data and makes different choices. When models from different providers land on the same answer, that says more than one model sounding confident.
Variance
Ask the same question twice and you can get two answers. Comparing many models shows how settled a question is: one tight group, a split, or scattered replies.
Grouping
ORBA embeds every reply and clusters them by meaning. You see how big each group is, its most representative reply, and the outliers, on one screen.

Select
Pick from 450+ models across 60+ providers, loaded live from OpenRouter's catalog. Or start from a preset: Free, Efficient, or Best.
Query
One prompt goes to every selected model. Paid models run four at a time with automatic retries; free models are paced to OpenRouter's rate limits.
Group
Replies are grouped by meaning with embeddings, or by wording if you prefer to stay offline. A strictness slider sets how alike replies must be to share a group.
Compare
The largest group's most representative reply becomes the consensus. Open any group to read its replies side by side, and export the whole session as Markdown.
What
It Does.
Models Available
Live count from OpenRouter, across 60+ providers. Free models to frontier ones, in one interface.
Ways to Measure Agreement
Meaning (embeddings) plus ten wording metrics: Jaccard, Cosine, ROUGE-L, BLEU-1 and more. Every score, for every model.
ORBA Fee
Bring your own OpenRouter key. It stays in your browser, you pay OpenRouter directly, and grouping by meaning adds a fraction of a cent.
Use
Cases
Research
Ask a factual question across many labs at once and see whether the answer is settled or contested.
Validation
Before trusting one model's answer, check whether models from other providers reach the same conclusion. Agreement isn't proof, but disagreement is a warning.
Analysis
See how many camps form, which models split off, and how each reply scores against the consensus.
